I have recently had a new combi boiler fitted Nd the lads have done cracking job however, it appears I may have a leak somewhere. I used to have to top the old boiler up quite regularly because if a leak on the manifold (hence the change) but since Saturday and the boiler swap I have had to top up the boiler already. I have a call out to the engineer but to be fair I'm expecting, " the boiler we fitted doesn't leak" and I feel it would be a fair comment...
I have checked all of my rads valves for anything obvious and they are dry and there are no signs of any leaks in any of ceilings. Ground floor is concrete floors so all the pipes are in loft or between ground floor and 1st floor. Any thoughts would be appreciated.
Thanks in advance.
